CAPACITOR-LESS LOW-DROPOUT VOLTAGE REGULATOR
International Journal of Electronics and Electical Engineering, 2014 A 1.2-V 40-mA capacitor-free CMOS low-dropout regulator (LDO) for system-on-chip applications to reduce board space and external pins is presented. By utilizing damping-factor control frequency compensation on the advanced LDO structure, the proposed LDO provides high stability, as well as fast line and load transient responses, even in capacitorfree ...

A DC Capacitor-Less Two-Terminal Unified Active Capacitor and Inductor
2022 IEEE Applied Power Electronics Conference and Exposition (APEC), 2022 <p>Flexible characteristics, tunable parameters, and improved power density are the desired attributes that have led to widespread research on active capacitors and inductors (ACI) in power conversion systems. However, the two-terminal realisation of ACI is challenging due to different trade-offs between power density, device stress, and ...
